A method and apparatus for transmitting data in a wireless communication system are disclosed, which transmit uplink data in consideration of mobile station (MS) consumption power such that a UE can be stably operated at a cell edge. A method for transmitting data by a mobile station (MS) of a wireless communication system includes transmitting, if MS power consumption is higher than limitation of power consumption, data to a base station (BS) with power higher than the limitation of power consumption using power supplied from a primary power-supply unit and a storage unit during a first time, and charging the storage unit using the primary power-supply unit during a second time, wherein the limitation of power consumption indicates maximum power amount capable of being normally supplied from the primary power-supply unit.

A method for multiplexing a data information stream and two types of control information streams in a wireless mobile communication system is described. The method includes mapping first control information in units of resource elements onto a matrix for generating input information mapped to a resource block, and mapping second control information onto the matrix so as to map the second control information to resource elements adjacent in a time axis to resource elements allocated for a reference signal in the resource block. The first control information is mapped downwards starting from the first row so as not to overwrite the resource element allocated for the reference signal.
